   Areas affected...Southern KY...Northern TN

   Concerning...Tornado Watch 48...

   Valid 122320Z - 130045Z

   The severe weather threat for Tornado Watch 48 continues.

   SUMMARY...Severe threat will focus across southern KY this evening.

   DISCUSSION...Longer-lived MCS that developed over the MO/IL region
   has progressed downstream into KY. This activity is predominantly
   north of a warm front that is advancing slowly north across the
   southern OH Valley. Strongest updrafts are concentrated along the
   southwestern flank of this broader area of convection as more
   buoyant inflow is feeding supercells from Butler-Warrent County.
   Given the observed shear vectors, and stronger instability noted
   across the TN Valley, storm motions should remain just south of
   east. As a result, the most favorable corridor for strong convection
   will remain across southern KY.
